Victorian drivers who haven't replaced their potentially deadly Takata airbags could have their registrations cancelled.
More than 400 registered vehicles in Victoria still have the defective Takata alpha airbags fitted, two years on from a compulsory national recall.
Road Safety Minister Jaala Pulford says car manufacturers have made repeated attempts to contact affected owners including by letter, phone, email and door knocking.
"We still have more than 400 vehicle owners who have not responded to the recall order," she said in a statement on Tuesday.
"We don't want to suspend or cancel anybody's registration, but we will do whatever is necessary to get these potentially deadly airbags off our roads."
Letters will soon go out to owners of any car impacted by the 2018 national recall warning them that it is their last chance to act before facing registration sanctions.
Cars affected include certain Honda Toyota, Nissan, BMW, Mazda and Lexus models built between 2001 and 2004.
Ms Pulford said affected owners should contact their local authorised brand dealer immediately to organise a replacement airbag at no cost.
It is believed there have been 29 deaths and more than 320 injuries worldwide from faulty Takata alpha airbags.
